@@johnjunior5421 as far as I know, yes

Then how come the bulb didn't burn out when I worked on it like that? but what i noticed is that the second time i put the bulb in it seemed to turn off the lamp ignitor automatically, i.e. it didn't do that red flash on the lamp ignitor at first, how is that explained?

@@johnjunior5421 Osram

You can find it on-line easily. Just search for Philips Master SON-T 70w lamp and I'm sure you can find it.

@@GunsGuy1990 i think it was dropped at some time. When I got this lamp, the arc tube was alteady like this

Mine, too, that's why I begun collecting them.

Thanks, great to hear that you started just like me

@@hpsnerd-ow6rcYup and you know i only love old street lights but New street lights sucks!

I was using them only for the short test period, but now I replaced them.

Doamne ajuta, la cât ne-a chinuit tronconica aia...

@@hpsnerd-ow6rc Pana vineri e gata si aia.

isn't it bad to touch these lamps without gloves? because I read that you shouldn't...

@@johnjunior5421 It's bad when they are hot.They can burn your skin. You should let it cool for 5 minutes,in the socket

@@johnjunior5421 also it's bad to touch the glass with greasy hands. But with clean hands it's ok, they are not like halogen lamps.

Yes, if the glass is already cracked, it can break due to the heat expansion. This can happening with all HID lamps. I have a mercury vapour lamp that was cracked durting the shipping and almost exploded after the second use.

Be careful with these experiments! the problem is not the mercury since it is in a small amount of about 12mg but the glass because they can injure you if it is new the lamp should I not worry?

Make a video with the sylvania shp-t basic plus 70w i have it and it's a very good lamp the philips mst son-t apia plus xtra will be interested

Yeah...so sad to see that even the HPS lamps are dissapearing nowadays...

neither can I believe that for so many years the roads were with sodium lamps, now they are these stupid LEDs with the tiring white light that disturbs the night, while the yellow was comfortable!

As far as I know is a chinese lamp from wich the romanian company bought the license.

I don't have one but I'm planning to get one because I'm also curious about the light colour

@@hpsnerd-ow6rc 2200K instead of 2000K and they probably have less blue and better cri

Yes, as I expected, it had the fastest restrike. Unfortunately, HPS can't beat LED in only one characteristic and that's power consumption...

Yes I also liked it very nostalgic 😢

It was so loud because wasn't screwed to the fixture because of the old Romlux ballast that you can see behind.

No, it's a Tesla SHC 250W from 1990. I was to lazy to take a SON-T lamp that was at the bottom of my lamp box :))

I think you have seen a Tesla 250w, is this is? It's such an old lamp, I wonder how you keep it and it hasn't burned out because HPS lamps usually live for 10-15 years rarely 20 years or more, only the mercury lamps are the ones that lasted many years but then they're useless! I've seen old mercury lamps that have a greenish color and very little light! It looks like you have antique type lamps :) I love them especially the HPS

Yes, is the same lamp from my early video. The only explication for the long life of the lamp is that it came from a new old stock. I remember that I got this lamp from a early 2000's street light that didn't existed in 1990 (Luxten Mira). And as far as I know, that lamp model came with Luxten LVST 250W hps lamps, not Tesla, so I think that the Tesla lamp was installed recently and wasn't in use for long.

Yes, every company was state-own util the fallen of the communism in December 1989. Now as far as I know it's a private company that is still making light fixtures. They provided the LED lamps in my hometown that were installed in the last year.

@hpsnerd-ow6rc Elgo had a really similar history. It was founded in the 50s i believe, then it was Polam-Gostynin until 1989, then it was Elgo owned by the state. In about 2006 it got bought out by a company named Brilium, they started doing shady businesses, tax evasion and the company went out of business in 2016. They used to make amazing fixtures like Elgo Strada, Elgo Acron, Elgo Leda

I didn't wear eye protection, I just did not look at it. But I used it only for the video, I never used it after.

@@hpsnerd-ow6rc Yeah, I see. Thank's for the reply. Maybe my eyes are sensitive or it is because of its power, anyways I can't be in the same room as my 400 watt bulb without tinted eyewear as the purple light alone hurts even if the UV is filtered out. And I also get the itchy feeling on the skin if I stay close to it for too long. It's the long wave UV that is breaking down the skin and accelerating its aging as well as increasing the chance of a melanoma happening later on. No sunburn though.

@@psirvent8 I got the same itchy feeling of the skin when I put my finger close to it. That's why I decided to keep it only for the collection and never use it again.

@@hpsnerd-ow6rc You can use it if you're far enough from it and protect your skin by wearing long sleeves and gloves. It's no worse than being outside on a sunny day.

just. know it. using hps as well. very good lightsource. i have rest of mosqitos but my neighbour under LED fixtures plays Macarena with mosqitos. i hearo ounli splat ouch splat ouch and myself surprised, whats going on?

I wish but I don't have any LPS lamps or ballasts. And here are very expensive.

I know that one costs 50 euros, unfortunately I don't have LPS either it's cool but I only have HPS Philips Son, son-t and Sylvania shp-t basic plus 70w and a mercury Poland. Bro I don't know but I really like your vibeos, you also have an icredible camera with a very high resolution. UV mercury lamp in this shape first time I saw it, i only knew fluorescent UV lamps

@@johnjunior5421 thank you very much! If it was only 50 euros... I found some Philips SOX lamps in my country at over 100 euros...

Yes, I love it !

Yes, it as hot as a normal MV lamp. Also if I hold my hand at about 3 meters from it, I'll get an itchy feeling from the UV radiation. It puts out a lot of UV.
